Unlike standard external drives, the HD720 does not require special care in terms of dust-proofing, so both travelers and professionals can use it worry-free.

Certification also means the HD720 is rated for up to 120 minutes of submersion in water at a depth of up to 2m. Hence even a drop into a body of water will not disrupt a cherished trip or a vital work task.

ADATA has also designed the HD720 to surpass the already-tough MIL-STD-810G 516.6 drop test: the drive can easily survive sudden and violent crashes and drops from as high as 1.8m, whereas the standard sets a 1.2m drop height.

The HD720 is coated in custom-weaved flexible silicone arranged in three layers for serious shock resistance of the type likely to be prized by anyone from mountain climbers to construction site personnel.

The drive features a smart G Shock sensor that halts drive read/write operation should a shock beyond a preset threshold occur. This prevents data corruption and loss, with drive operation resuming once the shock has subsided. Users are alerted to this with red and blue indicator lights.
